Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, specifically to a ventilation and air filtration integrated ventilation device. Background Technology

[0002] Currently, in today's society, with the continuous improvement of people's living standards and increasing attention to indoor air quality, ventilation and air filtration technologies are being used more and more widely in various buildings. A good ventilation system can effectively expel stale indoor air and introduce fresh air, maintaining indoor air circulation and comfort; while a high-efficiency air filtration device can remove pollutants such as dust, particulate matter, and harmful gases from the air, ensuring indoor air quality and creating a healthy and comfortable living and working environment for people.

[0003] Currently, most traditional ventilation systems only have simple air circulation functions, exchanging indoor and outdoor air through fans. However, they are poor at filtering air pollutants and cannot meet people's high requirements for indoor air quality. While air filtration equipment can purify the air to a certain extent, it often needs to be installed separately from the ventilation system. This not only takes up a lot of space, but also results in poor coordination between ventilation and filtration in actual use, making it difficult to achieve both ventilation efficiency and filtration effect simultaneously.

[0004] Therefore, how to provide a ventilation and air filtration integrated air exchange device to achieve efficient synergy between ventilation and air filtration is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0026] The various non-limiting embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 This utility model embodiment provides a ventilation and air filtration integrated air exchange device, which includes a duct fan 1 and a filter 2 connected to the air inlet end (i.e., the air intake end) of the duct fan 1.

[0028] The duct fan 1 includes a fan support 11 and an air guide shroud 12 connected to the fan support 11 near the filter 2.

[0029] A first receiving groove 13 is provided on the fan bracket 11 near the air guide shroud 12. A motor 131, a magnetic ring 132 coaxially sleeved on the motor 131, and a fan blade 133 coaxially sleeved on the magnetic ring 132 are arranged in sequence in the first receiving groove 13.

[0030] A second receiving groove 14 is provided on the side of the fan bracket 11 away from the air guide shroud 12. A circuit main board 141 and a back cover 142 for sealing the circuit main board 141 are arranged in sequence in the second receiving groove 14.

[0031] In this embodiment, efficient synergy between ventilation and air filtration is achieved through an integrated design. Specifically, the direct connection between the duct fan 1 and the filter 2 ensures that air is purified by the filter 2 before entering the duct fan 1, effectively removing pollutants and ensuring that the air entering the duct fan 1 is already in a relatively clean state. This structural design avoids the secondary air pollution problem caused by the separation of ventilation and filtration in traditional equipment, improving the efficiency and quality of air filtration.

[0032] Inside the duct fan 1, the structural design of the motor 131, magnetic ring 132, and fan blades 133 makes power transmission more direct and efficient, reducing energy loss. The compact layout also reduces the overall size of the equipment. Furthermore, the design of the air guide shroud 12 effectively guides airflow, allowing air from the filter 2 to enter the duct fan 1 more smoothly, further improving ventilation efficiency.

[0033] The circuit board 141 (which is electrically connected to the motor 131) and the rear cover 142 provide stable electrical control and good sealing protection for the operation of the duct fan 1, ensuring the reliability and stability of the equipment during long-term operation.

[0034] Through the above structural design, the ventilation device of this utility model not only achieves efficient coordination of ventilation and air filtration, but also has the advantages of compact structure, low energy consumption and stable operation, which can provide users with a healthier and more comfortable indoor air environment.

[0035] Furthermore, in one embodiment, the ventilation and air filtration integrated air exchange device includes a support column 134 extending outward from the axis of the first receiving groove 13 on the fan bracket 11. The support column 134 is a hollow structure with openings at both ends, and its bottom opening is closed by a bearing cover 135. A rotating shaft cavity 136 is formed inside the support column 134, and the motor 131 is coaxially sleeved on the support column 134.

[0036] A rotating shaft 137 is provided at the axis of the fan blade 133. One end of the rotating shaft 137 near the second receiving groove 14 is connected to the cavity wall of the rotating shaft cavity 136 through a second bearing 138, and the other end of the rotating shaft 137 away from the second receiving groove 14 is connected to the cavity wall of the rotating shaft cavity 136 through a first bearing 139.

[0037] Furthermore, in the ventilation and air filtration integrated air exchange device, the fan bracket 11 is provided with a power line 15 and a speed controller 16 connected to the circuit board 141.

[0038] In practical implementation, the structure and performance of the ventilation device have been optimized through further design in this embodiment, achieving a more efficient, stable and controllable synergistic effect of ventilation and air filtration.

[0039] First, by setting a support column 134 on the fan bracket 11 and coaxially connecting the motor 131 to the support column 134, and simultaneously using the first bearing 139 and the second bearing 138 within the shaft cavity 136 to support the shaft 137 on the fan blade 133, this structural design ensures the coaxiality and stability of the motor 131 and the fan blade 133, reduces vibration and noise during operation, and improves the durability and reliability of the equipment. Furthermore, the hollow support column 134 with openings at both ends and the internal shaft cavity 136 provide stable rotational support for the shaft 137, further optimizing power transmission efficiency and ensuring that the fan blade 133 can operate efficiently and smoothly, thereby improving ventilation efficiency.

[0040] Secondly, the power cord 15 and speed controller 16 provide the ventilation device with flexible power access and speed adjustment capabilities. The power cord 15 ensures a stable power supply, while the speed controller 16 can flexibly adjust the speed of the duct fan 1 according to actual usage needs and environmental conditions, thereby achieving precise control over ventilation volume and air filtration efficiency. This design not only improves the applicability and flexibility of the equipment but also allows for dynamic adjustment of the operating status based on changes in indoor air quality, further optimizing energy consumption and filtration efficiency.

[0041] Through the above structural design and functional optimization, the ventilation device in this embodiment has been significantly improved in terms of the synergy between ventilation and air filtration, operational stability, noise control, and operational flexibility, providing users with a more efficient, energy-saving, and comfortable indoor air environment.

[0042] Furthermore, in one embodiment, the ventilation and air filtration integrated air exchange device, wherein the filter 2 is mainly composed of a filter cylinder 21 and a bottom cover 22, the filter cylinder 21 is a hollow structure with openings at both ends, one end of the filter cylinder 21 is closed by the bottom cover 22, and the other end of the filter cylinder 21 is connected to the air guide shroud 12.

[0043] Furthermore, in the ventilation and air filtration integrated air exchange device, the filter cylinder 21 is mainly composed of an inner mesh layer, an outer mesh layer, and an activated carbon layer disposed between the inner mesh layer and the outer mesh layer.

[0044] In practical implementation, the structure and filtration performance of filter 2 were optimized through further design in this embodiment, which significantly improved the efficiency and effectiveness of the ventilation device in air filtration.

[0045] First, filter 2 mainly consists of filter cartridge 21 and bottom cover 22. Filter cartridge 21 is a hollow structure with openings at both ends. One end is sealed by bottom cover 22 (a sealing strip can be installed at the connection), and the other end is connected to air guide shroud 12 (a sealing strip can be installed at the connection). This structural design ensures that air must pass through filter 2 for purification before entering duct fan 1, ensuring the mandatory and efficient air filtration. At the same time, the direct connection between filter cartridge 21 and air guide shroud 12 reduces air leakage and backflow during airflow, further improving filtration efficiency.

[0046] Secondly, the filter cartridge 21 mainly consists of an inner mesh layer, an outer mesh layer, and an activated carbon layer sandwiched between them (of course, an absorbent layer, such as one made of absorbent resin, can also be placed between the inner and outer mesh layers). The inner and outer mesh layers effectively intercept large particles of dust and impurities in the air, preventing them from entering the activated carbon layer, thereby extending the service life of the activated carbon. The activated carbon layer has a strong adsorption capacity, effectively removing harmful gases, odors, and fine particulate matter from the air, such as formaldehyde, benzene, and volatile organic compounds (VOCs), further improving the air purification effect. This multi-layered filter cartridge 21 design not only achieves multi-stage air filtration but also improves the overall performance of the filter 2, enabling it to meet higher standards of air filtration requirements.

[0047] Through the above design, the filter 2 of the ventilation device in this embodiment is more compact in structure and has better sealing performance. At the same time, the filtration performance is significantly improved, which can effectively remove various pollutants in the air and provide users with a healthier and cleaner indoor air environment.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely examples illustrating several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be understood that the application of this utility model is not limited to the examples described above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
